Re: Fuel pump , Lack of power

["content22207" <brobertson@xxxx>]

Pump does not engage until engine is running certain number of RPM's
(anyone know what it is?). Safety feature I guess. That's why the
accumulator is so important -- until your car starts it's the only gas
available. One of my long term goals is to rig up a momentary switch
under the dash to jump Brown (hot) to White/Purple (line out) on the
fuel pump relay for the eventual day my own accumulator dies. 

BTW: fuel pump relay isn't in the two banks w/ headlights etc. Is last
relay under metal plate adjacent to wheel well (closest to engine
compartment).

The Buzzing Thingy in the engine compartment is probably your idle
speed motor (on driver's side intake rail). I don't have a Lamda valve
(passenger valve cover) so don't know what it sounds like, but Martin
G likens to an angry cricket.

Does car run without jumping pump (after started), or do we need to
trouble shoot your RPM relay? Don't have my factory manual with me,
but I seem to remember tachometer runs from relay (anybody?) -- if so,
should be quick visual diagnosis from dash.
